Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm given this problem:

Find conditions for variables a, b, c so that the limit

[tex]

\lim_{[x,y] \rightarrow [0,0]} \frac{xy}{ax^2 + bxy + cy^2}

[/tex]

exists.

What I have only found so far is that for all variables non-zero the limit doesn't exist. Anyway, I have no clue how to find the conditions for which it does. I tried a = b = c = 0, but it doesn't seem to help to me...

Thank you for the enlightenment.
